Root/toolchain/gcc/patches/4.6.3/002-siginfo_t.patch

1There is one usage in boehm-gc/os_dep.c, but it is only used if
2SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
3FREEBSD is defined, which are all not using Linux-based glibc ports.
4
5Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
6__FreeBSD__.
7
8config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
9config/s390/linux-unwind.h also uses a constant.
10
11I tested the following patch for sh-linux-gnu. This only covers one
12configuration, but the change is pretty mechanic anyway and every place
13that used to refer to struct siginfo already must have had <signal.h> in
14its include path, which is the same file that declares siginfo_t.
15
16OK to commit? This should probably also go into any active release
17branches, to keep them buildable once this glibc change ripples through?

20        * config/alpha/linux-unwind.h (alpha_fallback_frame_state): Use
21        siginfo_t instead of struct siginfo.
22        * config/bfin/linux-unwind.h (bfin_fallback_frame_state): Likewise.
23        * config/i386/linux-unwind.h (x86_fallback_frame_state): Likewise.
24        * config/ia64/linux-unwind.h (ia64_fallback_frame_state)
25        (ia64_handle_unwabi): Likewise.
26        * config/mips/linux-unwind.h (mips_fallback_frame_state): Likewise.
27        * config/pa/linux-unwind.h (pa32_fallback_frame_state): Likewise.
28        * config/sh/linux-unwind.h (shmedia_fallback_frame_state)
29        (sh_fallback_frame_state): Likewise.
30        * config/tilepro/linux-unwind.h (tile_fallback_frame_state): Likewise.
31        * config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Likewise.
